Could all the myths of the Buddha story, was actually some symbolises of the Buddha? For eg, there were lotus lotus flower blooming from the ground when baby prince siddhattha walked oon the 7 steps, symbolised the purity of the Buddha. The Brahma and devas holding the baby prince siddhattha, symbolised the noble of the Prince Siddhattha(later the Buddha) or symbolised the Prince Siddhattha(later the Buddha) was respected by the nobles. The words "I‘m the cheif of the world…" spoken by the baby siddhatha symbolised the noble and mighty of his future. I‘m not sure whether am my prediction correct or wrong. I think all this myths that don‘t seem possible in realistic life, might only be the symbols and metaphor that describes the Buddha.
In some story, Prince Siddhartha was born under the right arm of his mother,Queen Maya.This does not seems right to logically and is hard to believe. But if you have understand some of the cultures of India; this will be easier to understand. In India, there are cultures of 4 classes in the society. The highest class is the Brahmins ( families of Brahmin priests), 2nd class is Kshatriyas (families of royals and warriors), 3rd class is Vaishyas (families of skilled traders, merchants), and lowest class is Shudras (unskilled workers). It is pass down by the lineage of the family; that means the descendants from a lowest class family will always be in the lowest class in his whole lifetime, the descendants from the higher class family will always be in the higher class, regardless of his acquired efforts he have made.The lineages are pass down through generations, that means if the grandfather is a lower class people, his children, his grandchildren will also considered to be a lower class people in their lifetime. The higher classes will get more respect from others; where the lowest class will hardly get respect from others, especially it is hard to get respect from the highest classes. They believed that their religion the Brahma god created everythings,so in their cultures, to symbolize their classes; the highest class of Brahmins was say to be born from the mouth of Brahma God, 2nd class of the royals and warriors was say to be born under the arm of the Brahma God, the 3rd class of skillful people or merchants etc. was say to be born from the belly of Brahma god(this ones not too sure), the lowest class of servants was say to be born from the knees of Brahma god. Thus, in some stories saying that the Prince Siddhattha was born through the arm of Queen Maya , I think this was just to symbolise that he was from the 2nd class of the royals family; where in India traditional cultures, they symbolise the classes just as the 2nd class of royals and warriors was born through the arm if Brahma god. Therefore, I think this was just a symbolisation of the Buddha. Not really a baby was delivered from the arm of the Queen in realistic life.
Maybe in the olden days, people liked to describe things through symbolises and metaphor, instead of telling things in a straight forwards manner. Thus, all the myths of the Buddha, might be some symbolises and metaphors that represented the Buddha‘s life, his background, his thoughts and his teachings.
